Two trikes and a four wheeled SAR hand car,
National Railway Museum, Port Adelaide

The front car is a two person unit - on the broad
gauge, and the second car is a one man unit.

These cars were to be built from American Ash
(wheels) and Queensland Maple (frames). Information I have also
suggests that post 1932 all SAR cars were to have 5-ply centred
wheels. One wonders if this happened
